Does your bus use post style connections or stud style connections? This will make a big difference.
Sorry to barge in on your topic but I think I have to replace my starter batteries. They're just not holding a charge. So in reading up on what to do I notice you asked "post vs. stud" connections. Can you please describe the difference? I don't know which kind I have. And if I have "stud" instead of "post" what do I do?
My bus is a 1986 Carpenter GMC and right now it has two batteries on a tray that slides out. One of the batteries is sort of bulging which I'm guessing is the problem one, but I assume I need to replace both, right?
PS: Thank GOODNESS for this forum. I still don't know much about engines, motors, alternators, inverters -- but I'm definitely learning.
